There's a UK based site available for JB4, spark plugs etc if you really want them where no tax gets added. I was talking to them a while ago and also google verified that its a legit place. Prices came cheaper (not by toooo much though) compared to ordering from US and getting import tax etc.Kia Stinger Floor Mats All Weather (AWD models)
List Price: $140.00
Our Price: $119.95
This alone is ~$20 more then their price, and knowing sweden, the price will increase another 40% due to import tax and fees,etc etc.
This is one of the reason why i have not ordered JBL4, spark plugs etc because it becomes soo much more expensive to recive.
Kia Performance Parts
I am quite confident that if you write to them they will hook you up with a discount code too

Regarding the rubbery all weather mats, ask your dealership what the price would be, I bought mine from the official dealer in Estonia for about 120€ for front & back row.
